How to Make It
Preheat oven to 375°.
Combine first 5 ingredients in a large bowl, stirring well with a whisk. Lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and next 4 ingredients (flour through salt) in a medium bowl, and add flour mixture to sugar mixture, stirring just until moist. Pour mixture into a 9-inch square baking pan coated with cooking spray. Bake at 375° for 25 minutes. Cool in pan on a wire rack. Serve with raspberries.
